Describe the pathway through which pluripotent stem cells become differentiated into each type of cellular component in the blood. Be as specific as possible
What will be an ideal response?
Pluripotent cells differentiate into myeloid and lymphoid stem cells. Lymphoid stem cells differentiate into lymphocytes (B and T cells). Myeloid stem cells differentiate into megakaryocytes and precursors of erythrocytes, granulocytes, and monocytes. Megakaryocytes give rise to platelets, while the granulocyte precursors differentiate into neutrophils, eosinophils, and basophils. The erythrocyte precursors differentiate into reticulocytes, which ultimately become mature erythrocytes.
